Wetland Productivity  Understanding the link between inter-annual hydrologic dynamics and landscape modifications is prerequisite to modeling effects of climate and land use change on the function and productivity of prairie wetlands  Water level fluctuations are important processes that regulate productivity

12
Data Collection  Anteau and Afton (Wetlands 28:184-196) conducted surveys in 2004–2005 during a drying phase immediately following a prolonged deluge phase; these data should represent low amphipod densities  In spring 2010–2011 we revisited these wetlands as the landscape retuned to wet conditions; these data should represent high amphipod densities

30
Next Steps:  Continue to develop remotely-sensed prediction of Chlorophyll a  Examine landscape and community factors that influence Chlorophyll a and Amphipod density  Further investigate the potential of Chlorophyll a to predict Amphipod density
